Hi Stan,

A true 1" ID hard line would seem to be a real oddball. I don't recall 
ever seeing 1" Heliax before. There are a couple of things that could 
help identify the cable. One is the diameter of the center conductor. 
The other is a description of the dielectric material. Is it a solid 
foam, or is it mostly air with a helical dielectric spacer?

Since you identified the cable as "Heliax" is it fair to assume that the 
outer conductor is corrugated copper?
